The mouthpiece of the KK Dressage Weymouth is shaped to the anatomy of the horses mouth. It prevents pressure on the horses palate as the port is angled forward by 45. The pressure is evenly distributed on the whole tongue when the reins are pulled.
Less rein action needed as it is more direct due to the short cheeks. Sensitive rider hands are therefore important.
